The social networking site has confirmed to CNBC that it has removed more accounts associated with Alex Jones’s conspiracy website Infowars. Last month Twitter permanently banned both Jones and the Infowars website from its platform, citing violations of its behavior policies. But in that time multiple other accounts assisted with Infowars popped up on the service in an attempt to circumvent the ban. So far, Twitter has removed 18 such accounts and will be on the lookout for more.

Other tech companies have also banned Alex Jones and Infowars from their platforms including Google, Facebook, Apple, and PayPal. Jones is best known for his wild conspiracy theories, such as ones alleging the deadly 2012 Sandy Hook school massacre was a hoax.
